The souring and curdling of milk is caused by bacteria. These bacteria utilize all the nutrients, i.e., glucose and other vitamins, and produce acids as a waste product.
That's why milks go sour; it's because of the acids produced by bacteria.
Cheese was milk, which curdled but lavishly sprinkled with salt and compacted.
Although this is so, you cannot just put salt into your sour milk as commercial cheese uses cultured bacteria which are laboratory-tested for a specific use.
Making cheese from sour milk will just give you food poisoning.
